Among the high-efficiency metal-based catalysts, Cu is a star material profiting from its ability for CO₂ reduction into valuable hydrocarbon products. However, due to the difficulty in activating CO₂ and regulating intermediate adsorption/desorption properties, the CO₂RR activity and selectivity of Cu-based catalysts still cannot meet the requirements of industrial applications. The design of Cu-based bimetallic catalysts is a potential strategy because the introduction of the second metal can well promote the activation of CO₂ and break the linear scaling relationship in intermediate adsorption/desorption. In this review, the synergistic enhancements of Cu-based bimetals on CO₂ activation and intermediate adsorption/desorption are analyzed in detail, including the advantages caused by the morphology of Cu-based bimetallic catalysts, the local electric field effect induced by the special nanoneedle structure, the interface engineering (strain effect, atomic arrangement, interface regulation), and other particular effects (electronic effect and tandem effect). Finally, the challenges and perspectives on the development of Cu-based bimetallic catalysts for CO₂ reduction are proposed.</p></div>","PeriodicalId":100036,"journal":{"name":"Advanced Sensor and Energy Materials","volume":"1 3","pages":"Article 100023"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773045X22000231/pdfft?md5=75878c8dd1fe8db62b59657cb9c82a4e&pid=1-s2.0-S2773045X22000231-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"137439457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electrochemical imaging using scanning probe microscopy hardware has provided a method to visualize and understand processes that occur at the surface of ionic active materials. The suite of scanning probe microscopy techniques developed over the last few years are limited to imaging surface-level phenomena and have not been applied to investigate transmembrane properties of synthetic and natural membranes with high spatial and temporal resolution. In this article, we demonstrate the application our recently developed ‘surface-tracked scanning ion conductance microscopy’ technique to characterize voltage-regulated ion transport in an ionic redox transistor. The ionic redox transistor exhibits controlled transmembrane ion transport as a function of its electrochemical redox state. The technique presented in this article uses shear force measured between the nanopipette and ionic substrate to image topography of the porous substrate and simultaneously characterize topography-correlated transmembrane transport through the ionic redox transistor. The transmembrane conductance measured across an array of pores within the ionic redox transistor varies from 0.004 μS/cm (OFF state) to 0.015 μS/cm (ON state). We anticipate that the spatial correlation of transmembrane ion transport in the ionic redox transistor would result in a scale up into smart membrane separators for energy storage, neuromorphic circuits, and desalination membranes.</p></div>","PeriodicalId":100036,"journal":{"name":"Advanced Sensor and Energy Materials","volume":"1 3","pages":"Article 100026"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773045X22000267/pdfft?md5=8fcda49692b4caf258b973851e50ccf5&pid=1-s2.0-S2773045X22000267-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91045674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To seek suitable electrode materials with excellent NH₄⁺-storage is still in the exploratory stage and full of challenge. Herein, an inorganic-polymer hybrid, poly(3,4-ethylenedioxithiophene) (PEDOT) intercalated hydrated vanadium oxide (VOH), named as VOH/PEDOT, is developed to tune the structure of VOH for boosting NH₄⁺ storage. By the intercalation of PEDOT, the interlayer space of VOH is increased from 11.5 Å to 14.2 Å, which notably facilitates the rapid transport of electrons and charges between layers and improves the electrochemical properties for NH₄⁺ storage. The achieved performances are much better than progressive NH₄⁺ hosting materials. In addition, the concentration of polyvinyl alcohol/ammonium chloride (PVA/NH₄Cl) electrolyte exerts a great impact on the NH₄⁺ storage in VOH/PEDOT. The VOH/PEDOT electrode delivers specific capacitance of 327 F g⁻¹ in 1 M PVA/NH₄Cl electrolyte at −0.2–1 V. Furthermore, the quasi-solid-state VOH/PEDOT//active carbon hybrid supercapacitor (QSS VOH/PEDOT//AC HSC) device is assembled for NH₄⁺ storage, and it exhibits the capacitance of 328 mF cm⁻² at 1 mA cm⁻².
